I only regret the spelling error, FYI. As for the comments from DKzzzz, it's obvious from his remarks that he is either blowing smoke or is unable to properly setup his system. Until he posts his system we can only guess as to the reasons for his less than stellar results. I respect opinions of others who present themselves with intelligent and well thought out reasons for their likes and dislikes. Many manufacturers make quality components. I have enjoyed a wide range of products over the years...DKzzz's rantings sound suspicious and biased. Me thinks he might not have purchased a 400xi at all! If he did, it was most likely used.
